The main supporting structure of the tower consists of 16 curved, radially arranged laminated timber beams made of larch. In the upper part, a dense network of steel diagonal bars provides the necessary bracing, while in the lower part, four steel hollow section crosses, resistant to tension and compression, are anchored to the timber arches. The attached wooden spiral structure is supported by steel suspensions and steel transverse beams. Calculations were performed according to the second-order theory, resulting in a compressive force of 1160 kN and a maximum horizontal deformation of 15.7 cm. Planning, structural analysis, and execution were carried out by WIEHAG GmbH from Altheim, Austria.
